Also I don't see any rubber bushings on that mount. That will result
in some vibration in the fuselage. Perry Mick mounted his engine

because of the ducted fan and it has a very noticeable vibration in
the cockpit.

I have included a drawing what we did about it. The Aluminum plate
that goes
through the oil pan does not touch any metal from the engine mount. We
made
on the lathe custom Nylon bushings and 2" X 1/4" strips from conveyor
belt top and bottom. How effective, we don't know?
I like your idea with the rubber mounts better.

Well that will do for very high frequencies. Its a little stiff for most
however. Why nylon in there and not rubber? I think you need rubber.

Paul

I think the reason for the Nylon bushings was that the rubber may not
hold up well  and get mushy from the heat, oil etc. Nylon seems to be a
realy  durable and will not alow the plate to move around too much. I
would have done it with 4 or 6 Barry mounts.
